Application filed June 19,1325; I Serial No. 38,135.

This invention relates to improvements in shuttles, particular yshuttles "for carpet weaving looms or similar machines, and it is theprincipal. object of the invention to provide novel andimproved'meansfor teeding the fibrous paper strand under a certain tension to themachine or loom.

Another object of thinvention is the provision of ashut'le equippcdwithnovel guiding means for the strand.

A further object of the invention is the.

provision ot strand pulley within the shuttle equipped with means forallowing a tensioning of the strand during the feeding operation and alimiting of the displacement of the pulley during the feeding and'tcnsioning operations.

These and other objects and advantages of the inventioi will become morefully apparent as the description thereof proceeds, and will then bemore specifically defined in the appended claims.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a top plan view of a shuttle constructed according to thepresent invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a fragmentary, sectional View of a tensioning means for astrand guide roller, according to the present invention taken on theline 33 of Fig. 2.

A shuttle 10 of the customary form, has its front and rear ends pointedand protected by metal mountings 11 and 12. The shuttle has the usualchamber 13 formed therein for the reception of the strand coil 14, heldtherein by means of a holder strap 15 pivotally attached at one end to atransverse pin 16 in a depression of the shuttle and engaging at itsopposite end a depression 17 ot the shuttle and adapted to be held andlocked therein by means of a transverse pin 18.

The strand is guided in the shuttle around a pulley roller 19 inapproximately the center line thereof, and fed from the shuttle around amarginal pin 20 to the weft in the shed of the warp.

The strand tensioning device is illustrated enlarged in size in Figure 3in which the strand is guided about pulley 19 rotatably mounted on avertical pin 29 having an up- 331 screw head 30 and mounted with itslower threaded end in a boss 31 adapted to be displaced in an opening 32of a bracket 33 mounted transversely of the length of'the shuttle so asto move transversely to act as through a perforation inbracket 33.

Ata point oppositely disposed to the pin 36,,another pin 38 is threadedthrough an opening of the bracket and carries at its outer end anoperating knob '39, while its inner end is spaced from the boss 31 andis adapted to engage the same for limiting its movements in opening 32,to any desired degree.

It will be clear that in this manner a smooth edge of the rug and readyfeeding of the strand is ensured while its tensioning may be regulatedby the suitable and proper manipulation of pin 36 and spring 35 attached to the boss 31, the movements of which may be limited by theproper setting of pin 38.

lit will be-understood that while I have shown and described thepreferred forms of my shuttle as an example of the many ways ofconstructing the same, such changes may be made in its construction asfall within the scope of the appended claims without departure fromthe'spirit of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is:

1. In a shuttle, strand guiding means com prising a pulley, a pin inwhich said pulley is rotatably held, a movable boss to which said pin issecured, a bracket having an opening in which said boss can bedisplaced, a spring attached to said boss, an operating pin for saidspring to guide said boss in said opening tor tensioning the strandguided about said pulley, and a pin spaced from said boss and adapted tohe moved in said bracket to limit the movements of said boss.

2. The combination in a shuttle of a weaving loom, of a pulley rotatablysupported by a pin secured to a movable boss engaging in an opening, fordisplacement, in a bracket fixed within said. shuttle, a spring havingone end attached to said boss, and the other end to an operating screwfor adjusting the tension of said spring, and a limiting screw to adjustthe length of travel of said boss in said openin of said bracket foradjusting the tension of said spring, and a limiting screw to adjust thelength of travel of said boss in said opening.

a. The combination in a shuttle of a weaving loom, of a pulley rotatablysupported by a pin secured to a movable boss engaging in an opening, fordisplacement, in a bracket fixed within said shuttle, a spring havingone end attached to said boss, and the other end to an'opera-ting screwengaging in one side of said bracket for adjusting the tension of saidspring, and a limiting screw engaging in the diametrically opposite sideof said bracket to adjust the length of travel of said boss in saidopening.

5. The combination in a shuttle of a weaving loom, of a pulley rotatablysupported by a pin secured to a movable boss engaging in an opening, fordisplacement, in a bracket fixed within said shuttle, a spring havingone end attached to said boss, and the other end to an operating screwengaging in one 7 side of said. bracket for adjusting the tension ofsaid spring, and a limiting screw engaging in the diametrically oppositeside of said bracket to adjust the length of travel of said boss in saidopening, whereby said pulley will act as a slack take-up for the strandon the Weft in the flight of the shuttle.

In testimony whereof I have aiiixed my signature.
